Twist-Lock Barrels?

[LockNLoad]

Are these eventually going to be discontinued? I really like my twist-lock, but from everything I have seen AGD is converting over to Cocker threads.

Will manufacturers stop making twist-lock barrels altogether?

Some companies have already stopped making the Tlock barrels. They will eventually phase out as ULE bodies become more common. At least that's my prediction :)
